Definitions
- This invention relates to apparatus for and a method of routing signals on an internal powerline network.
- An internal powerline network is one that is substantially within a single premise.
- a powerline network to carry analogue and digital data signals.
- the data may be, for example, audio, visual and/or control signals.
- An example of such a network is described in U.S. Pat. No. 6,107,912.
- an internal powerline network has a fairly limited capacity for carrying such signals. When the number of units connected to an internal powerline network reaches a certain level the total data traffic can surpass the capacity of the network.
- apparatus for routing signals on an internal powerline network comprising a routing device for transmitting a signal on only a part of said network.
- a method of routing signals on an internal powerline network comprising receiving a signal at a routing device and transmitting said signal on only a part of said network.
- the routing device is connected to the fuse box/circuit breaker of the powerline network.
- Most premises have distinct circuits for different parts of the premise, such as different floors and different lighting circuits, and the routing through the fuse box can easily take advantage of this.
- FIG. 1 is a schematic view of a house with a number of units connected to an internal powerline network
- FIG. 2 is a diagram of a portion of the powerline network
- FIG. 3 is a schematic view of a routing device connected to a fuse box.
- a house 10 is provided with an internal powerline network 12 that, in addition to supplying power to units around the house 10 , carries data signals to and from those units.
- These data signals are typically audio, visual and/or control signals.
- a control signal is one that, for example, turns a unit on or off. The method of transmitting such data signals on a powerline network is well known in the art.
- an upstairs room 14 two such units are present, being a PC 16 and a television 18 (both shown schematically in FIG. 1 ).
- a second upstairs room 20 is a second television 22 .
- a second downstairs room 24 is a third television 26 .
- a routing device 30 connected to the fuse box 32 .
- the routing device 30 can receive a signal via the powerline network 12 and can route that signal by transmitting it on only a part of the network 12 .
- the routing device 30 creates data isolation between the circuits of the network 12 so that signals on one circuit do not necessarily appear on other circuits.
- the routing device 30 includes within it a storage device 38 that stores details of the units connected to the powerline network 12 and also details of the circuit of the network 12 on which each unit is located. This information can be programmed into the storage device 38 via a user interface 40 comprising keypad 42 and display 44 on the routing device 30 or the routing device 30 can periodically refresh the network 12 to determine which units are connected to the network 12 and their location. Other methods of keeping the information in the storage device 38 current are possible. For example each unit can be so arranged that when it is switched on at the mains it sends identifying information to the routing device 30 via the powerline network 12 .
- the units and the routing device 30 can operate an ethernet address system as the means for identifying and locating units on the network 12 .
- a unit When a unit wishes to send a signal via the network 12 to a second unit in the house 10 it will attach an identifier unique to the destination unit to the signal. This identifier is read by the routing device 30 which routes the signal (using information from the storage device 38 ) via the fuse box 32 onto the individual circuit on which the second unit is located.
- the routing device 30 can signal to the first unit that the signal has been correctly routed. For example if a user is playing a DVD on the PC 16 and also wishes to send the DVD signal to the television 26 in the downstairs room 24 then the routing device 30 , upon receipt of the DVD signal on the circuit 34 will transmit that signal via the fuse box 32 and circuit 36 to the television 26 . If the user, as an alternative, had wanted to send the signal to the television 22 then the routing device 30 would not have retransmitted the signal as the television 22 is already present on the circuit 34 and would receive the DVD signal without any need for the routing device 30 to take any action.
- the routing device 30 can also be connected to networks external to the house 10 , for example, to the Internet.
- the device 30 can be the connection point between the powerline network 12 and the external network and would therefore route the signals received from the external network onto the appropriate internal circuit.
- the powerline network 12 can also be connected to external networks via a unit on the powerline network 12 .
- the PC 16 may be connected to the Internet via a telephone line and a modem.
- the routing device 30 ensures that each circuit only carries signals which commence or terminate with that circuit.
